When I start my 740 in the morning and take it out, during the first 2 minutes or so the gears take long to shift. I would be driving 25 mph and the rpm would be still at almost 3 and wouldn't shift. It takes a while for it to come back to normal. What do you think this is from? I had a mechanic change the transmission oil for $200 and I am not sure if he did it right or if he put the right amount of oil in there. And the problem still occurs.
I want to change the transmission oil the right way, so I want to do it over.
Also, how can I get a BMW technical information system (TIS) CD?
